Spirometry
Tests of spirometry
| Question | Answer |
|---|---|
| Tidal volume (TV) | Volume of air inhaled and exhaled during a normal respiration (patient breaths in an out normally-lips pursed around mouthpiece) |
| Forced vital capacity (FVC) | Amount of air that can be forcefully exhaled from a maximum inhalation(Deep inhalation, quick and forceful exhalation until lungs emptied) |
| Forced expiratory volume in 1 second (FEV1) | Volume of air exhaled in the first second of the FVC |
| Expiratory reserve volume (ERV) | Maximal volume of air exhaled after normal exhalation (breath ina and out normally with forced exhale at end of the TV) |
| Inspratory reserve volume (IRV) | Maximal volume of air inhaled after normal inhalation (breath in normally, then forcibly inhale.) |
| Vital Capacity (VC) | Maximum amount of air that can be exhaled during a normal or slow exhalation after maximum inhalation (inhale deeply and exhale completely - compare to holding a long note when singing) |
| Inspiratory capacity (IC) | Maximum amount of air that can be inhaled after a normal exhalation (breathe in and out normally, then forcibly inhale at the end of the TV) |
| Function residual capacity (FRC) | Amount of air remainin in the lungs at the end of a normal exhalation) |
| Residual volume (RV) | Volume of air remaining in the lungs after a forced exhalation |
| Total lung capacity (TCL) | Maximum amount of air in the lungs with maximum inhalation) |
| Maximum voluntary ventilation (MVV) | Maximum volume that is breathed in and out in 1 minute (Breathe in and out as deeply and as frequently as possible for 15 seconds) |
